VFigure 6 is a sectional view taken substantially on line 6 6 of Fig. 3. Y

Referring to the drawings in detail the body portion of the tool, is indicated generally by the reference character 5 and comprises a pair of members connected by means of the rivets VIi, the rivets 6 also acting as spacers to maintain the members of which the body portion is constructed, in proper spaced relation with respect to each other.

The upper ends of the members are tapered as at 'I to be extended into the handle 8.

Slidably mounted between the members of the body portion 5, at a point adjacent to the lower end of the body portion, is a lifting arm 9 which is formed with an elongated opening I9 that accommodates the pivotpin II, whereby theA arm is pivotally and slidably mounted with respect to the body portion. One end of theY lifting arm 9 extends downwardly and is notched providing a lip I2 adapted to extend under the annular flange of the usual can closure that is held in position on a can by frictional contacttherev'vitlh.` The opposite end of the lifting arm 9"is formed'into a handle I3 so that the arm may be readily and easily manipulated `to properly adjust thel arm and jaw, forvarious sized caps or covers.` -The upper edge of the lifting arm 9 is formed with teeth I4,-for purposes to be hereinafter more fully described. It` might be further stated that the lower end of the body portion 5 is substantially widefand has a depending lip l5 providinga shoulder at its point of connectionwith the body portionfthe shoulder and lip being designed to t over one edge andthe upper surface'of the cap which is to be removed.

The operating handle of the tool is indicated by the reference` character I6 and is formed at one end of the pressure lever I8 thatis pivotally mounted between the members of the body portion, at I'I, the forward end of the lever I being extended downwardly and rearwardly, where it has pivotal connection with the link I9 that in turn has pivotal connection with the `link 20 which is also pvotally mounted between the members of the body portion. Pivotally con'- nected to one end of the link 29, is an armv2I which is formed with an opening to accommodate the lifting arm 9, the opening being appreciably wider'than the width of the lifting arm 9; to perfmit of free movement of the lifting arm 9 within the opening to permit the adjustment of the lifting arm 9 to be made with facility.

Teeth'22 are provided along one end of the opening of the arm 2I, the teeth being designed to engage teeth I4 of the arm `9`to prevent slipping of the arm 2|, when the operating handle is forced downwardly during the cap-removing'operation. A

A coiled spring indicated at 23 has one of its ends connected to the link 20 at a point beyond the pivot point of the link 29, the opposite end of the coiled spring being secured to the body portion 5. This spring will act to return the arm 2I and handle I6 to their normal positions after they have been operated to lift the can cover from the can.

Secured to the forward end of the arm 9, ad-

linger 25 which is offset with respect to the blade,

the guide finger being disposed directly above` the blade and spaced therefrom, so that the blade may be used in cutting Athe usual can top from a can, thereby providing a can-opening tool capable of removing various types of can closures.

In the form of the invention as shown by Fig. 3 of the drawings, the body portion of the opener is indicated by the reference character 26 and also embodies a pair of connected members formed with cut-out portions which, when the members are secured together, provide an opening for the arm 21 which is formed with an elongated opening 28 that accommodates the pivot pin 29 that is supported on the body portion, and extends across the opening. Thus it will be seen that due to this construction, the arm 21 may be moved forwardly, and then returned to the position as shown by Figs. 3, whereby the leverage will be appreciably increased.

The body portion is formed with a wide curved lip 29' which' is adapted to fit over one edge of a bottle cap, the lip being of a length to extend to the usual bead of a bottle, directly under the cap, as shown by Fig. 3.V Teeth 30 are formed directly above the lip 29 and are adapted to bite into the bottle cap to prevent slipping of the tool, when pressure is directed to the arm 21 in removing the cap.

The body portion is also formed with a depending nger 3| which has a. rearwardly curved cap-engaging portion 32 adapted to lit directly under one edge of the cap being removed.

A ch'ain indicated at 33', has connection with the body portion 2E, near the upper end thereof, the opposite end of the chain being secured to the arm 21, by means of thevcollar 33. By adjusting the arm 21 with respect to the Vbody portion, Various degrees of leverage may be provided.

Secured to the depending finger 3l of the body portion, is a blade 34 and a guide finger 35 directly thereabove, whereby the `device may be used for cutting out the top of the ordinary can, to open the can. A

'Ihe cap-engaging portion 32 is formed with a .plurality of substantially triangular lugs 36 of sizes to t Within the recesses or openings formed by the crimping machine in crimping the bottle cap in position. A corkscrew indicated at 31 is pivotally mounted on the arm 21. In operation, these lugs 36 will operate to prevent twisting of the cap to break the bottle, when excessive pressure is directed to the tool in removing the cap.

,From the foregoing it will be seen that due to the construction shown andA described, thearm B may be adjusted with respect to the body portion 5, to adapt the device for use in removing caps of various sizes. It will also be seen that because of this adjustment of the arm 9, the maximum leverage may be attained at all times, regardless of the size of cap being removed.

As the operating handle I6 of the device is forced downwardly, it will be obvious that a downward pressure will be directed to the arm 2| which in turn will cooperate with the teeth I4 of the lifting arm 9 to grip the latter arm and move same downwardly. This downward pressure forces .the body portion into close engagement with' one edge of the cap, while the lip I2 moves upwardly under the cap, prying the cap from its position on the jar or bottle on which it is located.
